Concrete-filled steel tubes (CFST) have been increasingly used in the construction industry
due to their favourable structural performance. With the increase of accidental events in the …

Fiber addition enhances the composite action between the steel tube and concrete core,
increasing the strength of the concrete core. To better understand how fiber-reinforced …

This paper presents the nonlinear finite element (FE) analysis of circular concrete-filled steel
tubes (CFST) with rubberized infill concrete (RuC) under flexure. The FE models were first …

This research investigates the performance of double C-purlin sections used in the concrete-
filled steel tube (CFST) beams system. A recycled-lightweight concrete was used as infill …

The flexural behavior of CFRP-strengthened circular concrete filled steel tubular (CFRP-C-
CFST) members was investigated experimentally and theoretically. A total of nine …

Recently, carbon fiber reinforced polymer (CFRP) materials have been recommended for
strengthening concrete-filled steel tube (CFST) members. In this paper, experimental study …

A comprehensive investigation of the flexural behaviour of concrete-infilled hollow flange
cold formed steel (CF-HFCFS) beams with lightweight normal and lightweight high strength …

A substantial number of experimental studies have reported on the flexural performance of
concrete-filled steel tube (CFST) beams. Due to the problem complexity, theoretically …

The flexural strength of Slender steel tube sections is known to achieve significant
improvements upon being filled with concrete material; however, this section is more likely to …

The outward steel tube buckling failure of concrete-filled steel tube (CFST) beams is still
considered to be a serious concern due to the typical bending loads. This research conducts …
